摘要：
Vanadium substituted Sm-10(Fe,V)(90) alloys were prepared by a single roller rapid-quenching method. The melt-spun Sm10Fe82.5V7.5 alloy showed the TbCu7-type structure for a wide range of wheel speeds between 15 and 50 m/s, while the Sm10Fe90 binary alloy showed the same structure at wheel speeds over 45 m/s. It was found that the substitution of vanadium for iron in Sm-10(Fe,V)(90) alloys gives a greater range of stability of the TbCu7-type structure. Nitrogenation was carried out by heating alloy powders in nitrogen gas. The magnetic properties of Sm10Fe82.5V7.5N, powder nitrogenated at 773K for 6 h were: J(r) = 0.71T, H-cJ = 535 kA/m (6.7 kOe), and (BH)(max) = 63.7 kJm(3).
